The Texas Triangle is one of eleven so-called "megaregions" in the United States. These are urban areas that are much greater in scale than just a metropolitan statistical area (MSA), defined by the US Census Bureau. These regions also are known as megapolitan areas. The term comes from the fact that the three main cities in the Texas Triangle are connected by a highway system Interstate 45, Interstate 10, and Interstate 35 that forms up a triangle when connected.
